Product Description:

LDPE Geomembranes

Products Description

   This product is extruded PE membrane formed by adding anti- oxidant, absorbent of ultraviolet and dyestuff into HDPE or LDPE or EVA and will provide an effective barrier to of liquid

water and water vapor.

Characteristics

·HDPE performs well in mechanical properties ,ageing-resistance , chemical-resistance ,climate- resistance and

resistance to puncture .

·LDPE & EVA feathers great elongation, good flexibility at low temperature, softness and easy

installation.

·ECB ,high-class waterproofing rolls, is formed by combining ethylene polymer with oil-resin.

Q:What is called a waterproof roll dry shop, wet shop
The biggest difference between the two is the same bonding strength, wet pad bonding strength is much larger than the dry shop method.
Q:Is the asphalt waterproofing membrane facing the side?
3, Summary: normal self-adhesive waterproof, the bottom of the membrane bonding surface facing the surface, the wall toward the back of the water; pre-shop anti-stick, the bottom of the membrane surface facing the back surface, wall is also facing the water.
Q:BS waterproofing membrane is modified? There are not a few thick drawings, how to do
SBS waterproofing membrane is elastomer modified asphalt waterproofing membrane. Performance indicators Implementation of GB 18242-2008.
Q:Construction Measures for Waterproof Coil in Winter
2. Master the hot melt paving points. Hot melt coil construction requirements of the heating width should be uniform, heating nozzle from the coil surface to be appropriate, 0.5m or so. Winter construction temperature is low, hot-melt time than the room temperature to be more, hot-melt to the surface of the membrane is bright, or melting is not enough. Such as beyond the degree of light overheating melting, the polymer modified asphalt easy to aging zoom, adverse bonding, but can not penetrate burned, grasp the hot melt to be strong bonding. When the sheet is rolled, the seam must be spilled over the adhesive to verify that the paste is tight, and the spilled adhesive is scrapped and the necessary measures to strengthen the seam. Coil large hot melt paving the same attention should be paid to the air inside the coil.
Q:Asphalt composite tire flexible membrane is SBS
SBS waterproofing membrane implementation of standards: GB 18242 (2008) "elastomer modified asphalt waterproofing membrane" Asphalt composite tire flexible membrane implementation of the standard: JCT 690 (2008) "asphalt composite tire flexible waterproofing membrane" Sometimes the composite tire coil also refers to several other rubber modified membrane.
Q:How to distinguish whether the waterproofing membrane is polyester tires?
Polyester tires (polyester fabric, polyester felt, polyester linoleum fabric) with high strength, high extension and puncture resistance, light weight, high tensile strength, good permeability, high temperature, anti-freeze, anti-aging, corrosion. Technical requirements, including the appearance of quality, intrinsic quality assessment projects and internal quality reference project, the indicators are in line with the provisions of the waterproof standards. Routine project tests should be in accordance with national standards test methods, thermal stability, bending, impregnation, water resistance test methods have done a detailed test.
Q:What is the meaning of the node and the additional layer in the construction of the membrane waterproofing layer?
Waterproof membrane construction, the node is relative to the large area of the plane in terms of. Node parts are: yin and yang angle, the root of the pipeline, the rain shed, all kinds of flooding, expansion joints, deformation joints, construction joints, through the wall and other areas need to focus on processing.
Q:What is the preferred level of waterproofing?
2, roof 2 waterproof: Applications: important buildings and high-rise buildings; Waterproof layer of reasonable use of life: 15 years; Waterproof layer selection of materials: should choose high polymer modified asphalt waterproofing membrane, synthetic polymer waterproofing membrane, metal sheet, synthetic polymer waterproof coating, high polymer modified asphalt waterproof coating, fine stone concrete, flat tile, linoleum Tile and other materials; Fortification requirements: two waterproof fortification.
Q:Why is the top cover of the basement waterproofing? While the floor has to empty shop?
Basement waterproof construction specification. Basement waterproofing acceptance specification.
Q:Pvc waterproof membrane of the scope of application
6, light color of the surface reflection of ultraviolet radiation, the surface of the membrane to absorb less heat, low temperature; 7, long life (roof 25 years, more than 50 years underground), and no environmental pollution; 8, the details of processing is very convenient, easy maintenance, low cost.
